Metrik – Real-time LLM performance monitoring

Summary: Metrik monitors Time to First Token (TTFT) for over 26 LLM models from OpenAI, Anthropic, Google, and xAI, providing real-time performance data and a free API to route requests to the fastest model.

What it does

Metrik tracks live latency across multiple LLMs and offers an API to direct queries to the quickest model for voice agents.

Who it's for

Developers building AI voice agents who need to optimize LLM response times.

Why it matters

It solves unpredictable LLM latency by enabling routing to the fastest available model in real time.
